Fig.' 113 indicates another'operationwhichunay ibe performed vvith't Qmyi-nventien; namely; cutting out and forming' reiforcingcarrying 'handles' -for cartons orl like'containers.

Referringfto' thevai'ieus views, my invention `is generally designated I4, and consistsfof-fassub- 4'stantiz'ally rectangular? handle element l5,-which, in *this instancafis indicated as f`-le'eing#made-f transparent f plasticrnaterial. The? handle, how- 40 f ever, 'may :be mdeff' anyI other? type `-of molding mate'rial.

""In' the1 molding f the?handleL-element t5; the leading cutting blade 25 -isfplaced'in the fml'd,

Which wil1 mainta-inf'fthebladei 5^andits cutting oblique cutting relationsh-ip'iwith'the exposed'putiting.- edge portionZ 1.

nfThe pilot'element 18g-Which is-"also'utilize'd for gauging the activity of the cutter by virtue of its gauging edge I9, is provided also with a pilot portion 20, which is pointed or pyramidal in construction. The said pilot element I8 is also made of moldable material, and the follower oblique cutter 2| is placed in the mold so that it will be rigidly embedded in the pilot element I8, and inasmuch as this is provided with an elongated slot 45, a web 24 will be formed, which will rigidly secure the cutter element 2| to the pilot element I8.

The cutter element 2|, or the follower cutter element 2|, is substantially of parallelogrammic conguration, and has an extended portion which will be secured to a slotted portion 46, formed in the ledge of the handle element I5, the same being assembled in the proper relationship indicated in Fig. l by virtue of grommets 23.

It will be noted that the cutting edge portion 21, and the cutting edge portion 22 are arranged in contra oblique directions in order to eifectuate compositely a complete cut through the thickness of the carton 3U.

The operation of the instrumentality is rather simple. The device is grasped in the hand as illustrated in Fig. 8. The pilot 20 is inserted into a corner 32 of the carton 3|), (see Fig. 3). The device is then manipulated across the edge of a carton S, and below the cover 3|, with the gauging edge Ie against the inner Wall of the carton section to be cut, and as the device is slid along in the direction shown by the arrow in Fig. 8, the greater portion of the carton section will be severed by the cutting edge 2l, and the operation will be completed by the cutting edge 22 working from the inner confines of the container. Thus, a complete dual contra bias cutting action takes place to eiectuate a clean cut.

The carton may he out to any suitable shape, as well as merely for opening to remove the contents.

I wish to stress that one of the important features of my invention is the fact that the pilot 20 permits the cutting operation to be initiated even with the most tightly glued or closed cartons, and by virtue of the inner gauging edge I9 of the pilot I8, no damage is caused to the contents of the carton, inasmuch as the cutting operation is effectuated with an action that tends to hold the cutting blade and the pilot away from the inner confines of the carton to protect the commodities or objects therein.

The item comprising my invention I may also be utilized for other purposes, as illustrated in Figs. 9-13.

In Fig. 9 a carton 33 may be severed by cutting along the lines 3d and 35 in order to form a suitable display for the contents therein. The cover 3G may be folded backward, as shown in dotted lines, and then utilized for effecting a complete closure of the carton 33.

Likewise, sinuous cuts or decorative cuts, as indicated in Fig. 10 and designated 3l, may be accomplished, with proper or slight manual dexterity in the handling of the carton cutter generally designated I4.

The instrumentality may ralso be utilized as indicated in Figs. 11 and 12, for cutting sections or segments 4] of corrugated board material 39, leather or other substances, against a guiding edge on a cutting board 38.

It may also be utilized as indicated in Fig. 13, after first forming two piercing openings 4I to permit the pilot I8 to be inserted, the device may then be manipulated along the line 42, cut- 4 ting out a section which may be folded back to form a reinforcing carrying handle 43 for cartons or containers.

In general, my device is of a simple construction, and it can be utilized to effectuate a cutting of cartons, corrugated cases, pasteboard boxes and like containers without damaging the contents therein.

It will also be noted that my device is of a simple construction, can be conveniently held in the hand, and manipulated to effectuate the various operations outlined in the drawings accompanying this application.

While the invention has been herein described in its preferred form it is to be understood that it is not limited to the specific construction herein shown and that it may be practiced in other forms without departing from the spirit and scope thereof.
